Emergency HVAC service in Toronto from ZK Mechanical costs the same after midnight as on a weekday afternoon: a $90–$150 diagnostic credited toward the repair, most fixes at $150–$800, and no overtime, weekend or holiday surcharge. The 24/7 emergency line reaches TSSA-licensed technicians who cover every part of the city.
24/7 Emergency HVAC Service in Toronto — Fast, Licensed, No Surcharges
A Toronto furnace failure becomes an emergency faster than a suburban one. Pre-war semis in Riverdale, Cabbagetown and Parkdale have supply plumbing on exterior walls and uninsulated brick, so at -15°C the kitchen pipes can freeze within hours of the furnace stopping; a 1950s Scarborough or Etobicoke bungalow over a crawl space is nearly as quick. Before you call, open the cabinet doors under sinks on outside walls, leave a tap trickling, and confirm the furnace switch and thermostat are on. Then call the 24/7 emergency line and tell us what the furnace does when it tries to start.
Winter calls split three ways. No heat with the furnace trying and failing to light is usually a flame sensor ($150–$300 to clean or replace), a hot surface igniter ($200–$450) or a pressure switch tripped by a snow-blocked sidewall vent — all fixable on the spot. No heat with nothing happening at all points to a control board ($500–$1,200) or a seized blower motor ($500–$1,500), and on a furnace past 15 years we'll say before ordering parts whether that money belongs in a replacement instead. A leaking water heater is the third call: a tank rusted through can't be repaired, and a like-for-like swap runs $1,200–$2,500.
Summer emergencies are cheaper than they feel. Most AC failures are a capacitor or contactor at $150–$350, a clogged condensate drain at $150–$350, or a coil frozen behind a filter nobody changed before the heat wave, and the repair range of $150–$800 applies day or night. Where many companies bill an after-hours dispatch fee of $150–$300 instead of the $80–$150 daytime rate, we bill one price. Two situations we won't troubleshoot by phone: if you smell gas, leave the house and call Enbridge Gas; if a CO alarm sounds, get everyone outside and call 911 first, then us.

Emergency Services in Toronto — FAQs
What counts as an HVAC emergency in Toronto?
Call right away for no heat below freezing, a CO alarm, a gas smell (leave first, then call Enbridge Gas and 911), an actively leaking water heater, or no cooling during a heat warning with an infant, senior or someone ill at home. A furnace that runs but rattles, or an AC that's weak but working, can wait for a daytime slot and costs the same either way. What counts as an HVAC emergency covers the grey areas.
Do you charge extra for after-hours or weekend emergency calls?
No. Evening, weekend and holiday calls carry the same $90–$150 diagnostic and the same repair pricing as a weekday visit, written down before the work starts. Elsewhere in the GTA an after-hours dispatch fee of $150–$300 is common, against $80–$150 in business hours. Our emergency pricing answer compares how the fee structures work.
Can you get into my Toronto condo for an emergency repair?
Yes, once the building lets us. Towers in CityPlace, Liberty Village and along Yonge need a concierge sign-in and often a booked service elevator; tell the desk you have a heating or water emergency and most will expedite it. We fix the in-suite fan coil, thermostat, valve or heat pump. If the fault is the building's boiler or chiller, we'll say so, and you can push the corporation instead of paying for a visit that can't fix it.
How much does emergency furnace repair cost in Toronto?
Exactly what daytime furnace repair costs. Most faults land at $150–$800 once the diagnostic is credited; a draft inducer motor sits at $400–$900, a gas valve at $500–$1,000, and a cracked heat exchanger at $1,500–$3,000 is where we stop and talk about a new furnace instead. See furnace repair in Toronto for the part-by-part breakdown.
What should I do while I wait for an emergency technician in Toronto?
Keep the house from freezing: run a trickle from the taps farthest from the water meter, open cabinets on exterior walls, close doors to unused rooms and put a space heater in the room with the water lines. Don't keep relighting a furnace that has locked out more than once, and never heat with the oven. A fireplace helps only with the damper fully open and a working CO alarm nearby.
